Abstract

Est divulgué un dispositif d'affichage flexible. Le dispositif d'affichage flexible comprend un premier corps, un second corps, un écran flexible et un haut-parleur. Le premier corps comprend un cadre de décoration, une première unité de rayonnement sonore et une seconde unité de rayonnement sonore. La première unité de rayonnement sonore et la seconde unité de rayonnement sonore forment une sortie à travers laquelle le son (ondes sonores) du haut-parleur est transmis à l'extérieur du premier corps. L'écran flexible comprend une première région fixée au premier corps, et est pourvu de la seconde unité de rayonnement sonore tandis que la surface extérieure de la partie de bordure de la première région est espacée du cadre de décoration. Le son (ondes sonores) du haut-parleur est transmise à l'extérieur du premier corps par l'intermédiaire de la première unité de rayonnement sonore et de la seconde unité de rayonnement sonore, de telle sorte que la qualité sonore du haut-parleur peut être améliorée, et la seconde unité de rayonnement sonore peut être empêchée d'être exposée à l'extérieur.
